Refining the postprocessor for MASSO plasma cutter controller

Post by dave_mech »

Recently my company set up a CNC plasma cutting machine with MASSO controller. For the time being we've been working without THC, waiting it to be shipped. MASSO has on their website postprocessor files to load on the Sheetcam library, for both plasma cutters with and without THC, which is the one I've been using. But I can tell this potprocessor is far from perfect. I set the tools with their respective pierce and cutting heights, as well as defining a height for rapid movement in the work options. When I simulate the cuts, the torch height behaves as I intend. But then I run the post processor, it only respects the pierce and cut heights in the first cut, and in the rest it simply remains on piercing height: it shows the comment (---Go to cutting height---), but the Z coordinate is not provided. It also ignores the rapid movement height between cuts. As a result, I have to waste time editing manually the code to have the cut I want.

Here's how the code should be between two cuts:

Code: Select all

N0230 G00 Z10.0
N0240 X110.6988 Y146.8674
N0250 (---Go to pierce height---)
N0260 Z5.7000
N0270 M03 (---Torch ON---)
N0280 G04 P2000
N0290 Z4.6000 (---Go to cutting height---)
N0300 G01 F100.0
N0310 G02 X107.4988 Y143.6674 I-3.2000 J0.0000 F240.0
N0320 I0.0000 J7.2500 F435.0
N0330 X105.9903 Y145.9251 I0.3746 J1.8831 F240.0
N0340 M05 (---Torch OFF---)
N0350 G00 Z10.0
N0360 X174.0473 Y341.8340
N0370 (---Go to pierce height---)

But this is the code the postprocessor is producing:

Code: Select all

N0230 G00
N0240 X110.6988 Y146.8674
N0250 (---Go to pierce height---)
N0260 Z5.7000
N0270 M03 (---Torch ON---)
N0280 G04 P2000
N0290 (---Go to cutting height---)
N0300 G01 F100.0
N0310 G02 X107.4988 Y143.6674 I-3.2000 J0.0000 F240.0
N0320 I0.0000 J7.2500 F435.0
N0330 X105.9903 Y145.9251 I0.3746 J1.8831 F240.0
N0340 M05 (---Torch OFF---)
N0350 G00
N0360 X174.0473 Y341.8340
N0370 (---Go to pierce height---)


Also, I wonder how could I get the postprocessor to include the programmed coordinated system in the code, and to always send it at rapid movement height at the start of every code. Anyinsight would be much appreciated.

I attach the postprocessor file.

Yes. That post was a little messy. I have tried to improve it.
